What Does Mistaken Identity Mean?
Content TermA trope in which a character is believed to be someone — or something — they're not, and the plot runs on the confusion. Variants range from farcical twin swaps to a hero dating someone who doesn't know about the mask.
Mistaken Identity in Practice
Mistaken identity is ancient comedic machinery, inherited from stage farce and screwball comedy, and fandom uses it constantly because so many canons hand it free fuel: secret identities, doppelgangers, undercover missions, online anonymity. Superhero fandoms practically run on the version where someone loves both the hero and the civilian without realizing they're the same person. The trope's center of gravity is the reveal — readers stick around for the moment the truth lands and everything previously said gets recontextualized at once.
Example usage
"Classic mistaken identity setup: she's been trading flirty messages with her annoying coworker the whole time and has no idea."
